 Java 19 (preview)
 - due to the use of the new Foreign Function & Memory API
 
+# Usage
+The bindings come in two flavors:
+
+## Dependency including *all bindings* related to libappindicator:
+- gtk-3.0
+- glib-2.0
+- cairo
+- gdk-pixbuf-2.0
+- pango-1.0
+- atk-1.0
+- harfbuzz
+```java
+<dependency>
+    <groupId>org.purejava</groupId>
+    <artifactId>libappindicator-gtk3-full-java</artifactId>
+    <version>1.0.0-SNAPSHOT</version>
+</dependency>
+```
+
+As the according jar has a size of ~9,6M, I decided to provide a **reduced variant of the bindings**, see below.
